Definitions

  • the present disclosure relates to components of wheel and brake assemblies, and more specifically, to a multipart torque bar according to the preamble of claim 1.
  • Torque bars are typically used in aircraft wheel and brake assemblies to couple the wheels to the rotors of the brake assembly. Torque bars typically extend from an inner surface of the wheel in a direction parallel to the rotational axis of the wheel, and are subject to static and dynamic deflection and vibration. Torque bars of the prior art typically comprise a single-piece body having a bolted end and a slender pin end that is flexible. Torque bars are main structural components in the primary load path of the brake torque. WO 2009/082397 relates to a wheel and brake assembly with torque bar.
  • a multipart torque bar may comprise an outer torque bar body, an inner torque bar body, a mounting hole, and a connecting end.
  • Outer torque bar body may have a first end and a second end, a top surface and a bottom surface, and a groove. Groove may define an opening on outer torque bar body beginning on the first end of the top surface and extending in an axial direction proximate the second end.
  • Inner torque bar body may have a first end and a second end, and a top surface and a bottom surface.
  • Inner torque bar body may be configured to removably insert within the groove of outer torque bar body.
  • Mounting hole may be located on the top surface of inner torque bar body, by the first end of inner torque bar body.
  • Connecting end may be located on the second end of outer torque bar body.
  • a wheel and brake assembly may comprise a wheel, a brake assembly, and a multipart torque bar.
  • the wheel may have a radially inner surface and a connecting hole.
  • the multipart torque bar may comprise an outer torque bar body, an inner torque bar body, a mounting hole, and a connecting end.
  • Outer torque bar body may have a first end and a second end, a top surface and a bottom surface, and a groove. Groove may define an opening on outer torque bar body beginning on the first end of the top surface and extending in an axial direction proximate the second end.
  • Inner torque bar body may have a first end and a second end, and a top surface and a bottom surface.
  • Inner torque bar body may be configured to removably insert within the groove of outer torque bar body.
  • Mounting hole may be located on the top surface of inner torque bar body, by the first end of inner torque bar body.
  • Connecting end may be located on the second end of outer torque bar body.
  • the multipart torque bar may be coupled to the radially inner surface at the mounting hole.
  • the connecting end may be coupled to the connecting hole.
  • a method for installing a multipart torque bar onto a wheel and brake assembly may comprise inserting an inner torque bar body into an outer torque bar body to form the multipart torque bar.
  • Outer torque bar body may have a first end and a second end, a top surface and a bottom surface, and a groove. Groove may define an opening on outer torque bar body beginning on the first end of the top surface and extending in an axial direction proximate the second end.
  • Inner torque bar body may have a first end and a second end, and a top surface and a bottom surface.
  • Inner torque bar body may be configured to be removably inserted within the groove of outer torque bar body.
  • the wheel may comprise a radially inner surface and an at least one tie bolt hole.
  • the method may also comprise coupling the multipart torque bar to the wheel.
  • any of the method or process descriptions may be executed in any order and are not necessarily limited to the order presented.
  • any reference to singular includes plural embodiments, and any reference to more than one component or step may include a singular embodiment or step.
  • any reference to attached, fixed, coupled, connected or the like may include permanent, removable, temporary, partial, full and/or any other possible attachment option.
  • any reference to without contact (or similar phrases) may also include reduced contact or minimal contact. Surface shading lines may be used throughout the figures to denote different parts but not necessarily to denote the same or different materials.
  • a wheel and brake assembly 100 can comprise a wheel 102 having a radially inner surface 104.
  • a brake assembly 106 is disposed within wheel 102.
  • a plurality of torque bars 110 are oriented parallel to an axis of rotation 112 and coupled to wheel 102 and radially inner surface 104, and configured to engage with brake assembly 106.
  • the torque bar is a main structural component in the primary load path of the brake torque.
  • the torque bar may experience different modes of vibration.
  • mid-frequency whirl vibration typically a "wobble" motion occurring during high velocity landing stops
  • the torque bar exhibits a small amount of dynamic "whipping" or "jump roping,” i.e., movement radially inward and outward with respect to the axis of rotation, leading to lower stability margins.
  • Brake vibration can be a serious issue, and may result in damage to aircraft components if not properly managed. Any damping that can resist that motion may therefore be beneficial.
  • a multipart torque bar 110 may function to create damping by inducing relative sliding between the multiple parts to dissipate kinetic energy.
  • multipart torque bar 110 may create damping by inducing interfacial friction on the interfaces of the parts of multipart torque bar 110. Interfacial sliding and friction creates damping which may be beneficial to lower the vibration level in multipart torque bar 110. For example, when multipart torque bar 110 experiences "jump roping" vibrations, components of the multipart torque bar 110 will slide and rub during the motion, damping the vibration.
  • multipart torque bar 110 may comprise an outer torque bar body 330, an inner torque bar body 320, a mounting hole 323, and a connecting end 340.
  • multipart torque bar 110 may be made using any suitable process such as, for example, machining, investment casting, and or the like.
  • multipart torque bar 110 may be made by additive manufacturing processes, such as, for example, fused deposition modeling, polyjet 3D printing, electron beam freeform fabrication, direct metal laser sintering, electron-beam melting, selective laser melting, selective heat sintering, selective laser sintering, stereolithography, multiphoton photopolymerization, digital light processing, and/or any other suitable additive manufacturing process.
  • multipart torque bar 110 may be made of any suitable material.
  • Multipart torque bar 110 may be made from any substantially rigid and durable material.
  • multipart torque bar 110 may comprise a metal material, such as steel or a nickel-based superalloy.
  • Multipart torque bar 110 may also have any suitable coating.
  • a suitable coating may comprise a coating that does not have a high coefficient friction such that the surfaces of multipart torque bar 110 would lock, but also does not have a low coefficient friction such that no friction would be generated on the surfaces of multipart torque bar 110.
  • a suitable coating may have a coefficient of friction value between 0.3 and 0.6.
  • a tungsten carbide cobalt coating may be used.
  • any other suitable type of coating may also be used.
  • the use of a coating may function to increase the friction between parts of the multipart torque bar 110, aiding in the damping effect.
  • an outer torque bar body 330 may be configured to support and receive an inner torque bar body 320.
  • Outer torque bar body 330 may have a first end 331 and a second end 332, and a top surface 336 and a bottom surface 337.
